This invention relates to a machine for use in forming glass vessels,receptacles or containers.

An important object of the present invention is the provision of amachine which has a rod for causing a wiping pressure on the molten rimof a glass receptacle to form a lip or pouring spout thereon wherebyevery receptacle will be subjected to the same operation making everylip or spout the same in size, shape and contour.

Another important object of the present invention is the provision of a,lipping machine for forming a pouring lip or spout On glass receptacles,the machine having a rod which is adapted to be operated inan orbitalpath to provide a downward pressing wiping action against the molten rimof a container.

Still another important object of the invention is the provision of alipping machine having mechanism operable inlan orbital path to effect adownward pressing and outward wiping operation against a molten edge ofa glassvessel, the machine bein adapted to effect one continuousoperation to complete a cycle, and then automatically come to rest uponthe completion of said cycle.

A still further object of the invention is the provision of a lippingmachine having a base for supporting a, vessel thereon by suction, andmanually controlled gas means to fire the container to a predeterminedheat,,there being a manually operated handle which may be turned tocause the machine to'go through one single cycle to I2, although theshaft I I may be driven continubring a lipping rod into pressing andwiping engagement with the heated container to form a lip thereon.

Numerous other objects and advantages willbe apparent throughout theprogress of the specification which follows.

The particular device herein shown for the purpose of illustrating theinvention comprises .a supporting structure I which may be mounted' onwheels 2 to permit the machine to be moved from one location to another.The structure I has a lower shelf 3 and a top 4. The shelf 3, Fig. 1,supports a motor 5 which drives a sprocket 6 the gearing case I. drivenby the sprocket 1, drives a driven sprocket 9 which is mounted on ashaft I0. The shaft It is mounted rotatively in suitable bearingscarried by the structure top A. The shaft IE! is adapted to drive ashaft II which is in alignment with the shaft I0, the shaft II beingdriven by the shaft It through clutch mechanism I2. rotated continuouslywhile the shaft I I is adapted to be driven intermittently through theclutch ously should the occasion arise.

The shaft II carries a sprocket I3 which drives a sprocket chain I4trained over a sprocket I5 fixed to a transverse shaft I6. The shaft I6also has a second'sprocket I'I fixed thereto anddrives a second shaft I8by means of a sprocket chain I9 trained over the sprocket I1 and. asprocket which is fixed to th shaft I8. The shafts I6 and I8 aresuitably and properly journaled rotatively in spaced brackets 2| and 22which are secured to the top c.

A member 23 which acts as a crank is attached to the shaft II. A pin 24is secured to a face of the member 23 and drives a link or arm 25 whichis pivotally mounted on the pin 24. The

link or arm 25 is pivotally connected at 26 to one end of a bar or rod2?, the outer end 28 of said rod erforming the lipping operation to forma lip 29 on a glass container 33, Figs. 6 to 11. The bar or rod 21 hashorizontal slidable or reciprocating movement in a guide sleeve 3| whichis guided for vertical movement on spaced guide rods 32 and 33,.verticalholes being provided in'the guide sleeve or block 3| to receiveslidingly said rods 32 and 33. The rotation of the shaft II causeshorizontal reciprocation of the. bar or rod 21 by parts 23-to 26. havevertical, or up-and-down,

The rod. 2? also is adapted to in an orbital path in a vertical plane.

The end28 of rod 21 is givenvertical-movement by means The shaft I0 isadapted to be reason of the connections and movement so that, thelipping end .28 of the bar or rod 2'] will move of opposed guide wheels34 and 35 which are eccentrically mounted on the shafts in I 5 and I8,respectively. The wheels 34 and 35 act as cams, and their peripherieshave rolling contact with the guide block 3!, whereby the bar or rod 27will be raised and lowered upon rotation of the shafts l3 and I8. Thewheels'or cams 34 and 35 are positioned eccentrically in such a mannerthat there will always be the same distance between the adjacentperipheries thereof. The end 28 of the rod or bar 21 is thus givenvertical movement as well as horizontal movement, therefore, the lippingend 28 is movable in an orbital path in a vertical plane. The bar or rod2?, in rest or normal inoperative position, is retracted inwardly and atits highest elevation. The rod 21 then moves outwardly to its fullextent and projects into the open.ng of the glass receptacle 35 as shownin Fig. 8. The movements of the bar which follow are downwardly andinwardly so that there will be a downward pressure of the lipping endagainst the rim of the receptacle, as well as wiping action, so that theend 28 will form the molten glass progressively, Figs. 8 to 11,'to'formthe lip 29, Figs. 6, 7 and 11. The rod or bar assumes its rest orinoperative position after the completion of the lip forming operationand after the rod has been fully retracted inwardly.

The receptacle or container 35, to which the lip 29 is to be formed, ismounted on an adjust-- able base 36 and is held to the base by means ofsuction, there being an opening in the bottom ofthe base to which asuction line 31 is connected, and which suction line leads to a sourceof suction, Figs. 1 and 2. The base 36 has a rigid rod 38 connectedthereto which has slidabie movement in a block 39 and is, therefore,given vertical adjustment. The rod 33 may be locked in any adjustableposition by means of a set screw 40. The rod or bar 353 has pivotalmovement in the'supporting block 33, whereupon the base 33 may beshifted in an arc throughout various angles, as well as being movedinwardly and outwardly. Further vertical adjustable movement of the baseis given by means of a rod or bar 4| to which the block 39 is attached.The rod 4! has telescoping movement in a tubular base part 42. Thevertical movement of the rod 4! with respect to the tubular base part 42provides for considerable vertical adjustment, and the parts maybelocked in adjusted position by means of tightening a set screw 43. Thecontainer or receptacle 30, therefore, is positioned at the properheight and at the proper angle with respectto the lipping end 28 so thatvarious size lips may be formed and various sizes of receptacles orcontainers may be accommodated.

The receptacle is mounted on the supporting base 36 while it is stillhot from the forming thereof and is maintained in rigid position thereonby means of suction. The part of the container, where the lip 29 is tobe formed, is again heated by means of a gas jet 44, which is manuallycontrolled by a handle 45 to operate the gas valve -46. The burner 44 isconnected to ordinary gas, there being a shut-off valve in the gas line.However, for the heating operation, acetylene gas is mixed with theordinary gas, and the amount of the acetylene gas is determined by theposition of the valve 46. The valve is adjusted so that when theoperating handle 45 is operated,

the proper gas flame will come from the burner or jet 44. v

The machine, is so constructed and arranged that one complete cycle ofoperation will be performed for forming the lipping operation even meansof suction coming through thelline 31.

4 though the shaft I0 continues to run continuously. The shaft 1 l, therod 21 and the wheels 34 and 35 are caused to operate through one cycleof the operation and normally are at rest even though the shaft IDcontinues to rotate. The operation of the shaft H, and consequently theother parts controlled thereby, is brought about by means of the clutch[2. The clutch [2 comprises a bar in the shaft [0 and a plunger 41 whichis adapted to operate in a slot 48 formedin the shaft l0 and withrecesses or cutaways 49 formed internally about the periphery. Theplunger 47, Fig. 4, includes an extension or operating piece 50, Fig. 5,which extends outwardly and is normally pressed outwardly by a spring 5|so as to normally cause the plunger 41 to be pressed outwardly and bereceived in a recess 49 and, therefore, cause locking engagement betweenthe shafts H] and II. A control finger 52 mounted on a rod 53 is adaptedto engage the extension 50 while the shaft It is rotating, and,therefore, move the plunger 41 into the slot 48 and out of engagementwith the walls of the shaft [0 at the recess or cutaway 49. As soon asthe projection'50 of the clutch strikes the finger 52, the shaft II willbe disconnected from the shaft [0, whereby the shaft i6 may continue torotate but the shaft I I will remain stationary. To cause operation ofthe shaft II by connectins it with the shaft l0, a handle 54 on the rod53 is given a part turn so as to remove the finger 52 out of the path ofthe member 50. As soon as the finger 52 is no longer in engagement withthe extension 50, the spring 5| will move the plunger 41 upwardly intothe engagement shown in Fig. 4, whereupon the parts will again beconnected. -'The handle 54 is operated against the tension of a spring55 connected to an arm 56 on the end of'the rod. The rod 53 is operatedmanually by turning the handle, and when released, the finger 52 will bepulled by the spring 55 to return the finger 52 into position to againengage the projection 55. However, as soon as one rotation is had, theprojection 5! will again strike the finger 5 2 and cause the parts tobecome disconnected again, and the shaft II and. all the parts operatedthereby will remain at rest. The

parts will continue to. be at rest until the handle 54 is again operatedto shift the. finger 52 out of position to cause engagement of theclutch. The lipping rod or part-of the'fin'ger therefore will operate.during one complete cycle, and, therefore, the attendants may remove"the lipped container and insert another in position without hindrance ofany moving parts. The clutch 'is soconstructed and arranged that theparts will be in their disconnected position when the rod or arm 2'l isat its extreme upward and inward po sition. When the handle 54 isoperated, the rod or bar 27 will move inwardly anddownwardly to" justedposition and mounts a'receptacle thereon,

the receptacle being rigidly held onthe base by The handle 45 is thenoperated to produce. the proper gas flame to preheat the rim of the re'ceptacle at the point where the lip 29 is to be formed. As soon as theedge has received the proper amount of heat, theoperator shifts thehandle 54 -which will move away from the projection 5U, whereupon therod 27 will go through one cycle of operation. The operator merely turnsthe handle 54 until the parts are engaged, and then immediately releasesthe handle, whereupon one complete operation is performed and the partsfor operating the rod 271 will come to rest at the conclusion of onecycle.

The invention provides a lipping machine which is ambulatory whereby itmay be moved from position to position adjacent the glass formingmachine. The machine is adapted tobe adjusted at any proper height orangularity to accommodate vessels or receptacles of various types orkinds, as well as to form various size lips 29. The lipping is done inone complete operation by a machine that performs a single lippingoperation and goes through the same cycle upon the will of the operator.The lipping rod, going through the same operation and oper ating in thesame orbital path at all times, causes every lip of the containers beingrun to be the same. The machine is adapted to be controlled by theoperator and at such speed as suits the fancy and whim of the operator.The parts are so constructed and synchronized that the proper amount ofwiping pressure to the lipping end will occur through a. proper timeinterval so as to provide the proper kind and shape of lip desired orrequired. The machine is relatively simple in construction, may bereadily and economically manufactured, and is not likely to get out oforder. The slide supporting bearing 3! may be substituted by another sothat various size rods 21 may be accommodated. Also, the bearings inwhich the shafts l5 and is are mounted or supported may be adjustablesoas to accommodate bigger roller elements 34 and 35 to accommodate largeror smaller rods 21. In actual practice, however, it has been found thata single rod 21 may be employed for ail purposes because the lipping end28 is made detachable and, therefore, a lipping end 28 of the desiredsize may be substituted.
